Frequently Asked Questions

Q: Is this thrust bearing compatible with standard 3/4" bore clutches?

A: No, this specific bearing is designed exclusively for 1.0" ID big block clutch assemblies. Please ensure your crankshaft and clutch bore match this 1.0" specification before installation.

Q: Why is a thrust bearing necessary for my big block clutch?

A: Inside a high-torque racing clutch, axial forces can cause binding and premature wear. This bearing manages those forces, ensuring the clutch components remain aligned, which reduces friction and allows for smoother, more responsive shifting.

Q: How do I know when to replace my inner thrust bearing?

A: You should inspect the bearing during every major clutch rebuild. If you notice signs of heat discoloration, pitting, or if the bearing does not rotate smoothly, it should be replaced to prevent damage to your drive-line components.

Q: Does this bearing require special lubrication?

A: It is recommended to keep the bearing clean and lightly lubricated with a high-quality, heat-resistant racing grease to ensure it maintains integrity under the extreme temperatures found in power-hungry racing classes.
